Bi-Wire Flexi Fire Alarm Panel (Conventional or Bi-Wire Selectable Zones)

BiWire Flexi combines two technologies to provide a truly versatile fire safety solution.

The panel can be configured to allow either two-wire or conventional devices to work on a zone. Each zone is individually configurable so a mixture of types can therefore be installed on the same system. This provides you with the exibility to utilise all the time-saving benefits of a two-wire system with the ability to use a wide range of conventional devices, where required.

Flexi relieves the pressure of system selection. It is the perfect solution for electrical installers and distributors as it takes complexity out of the decision when specifying a fire system. It can be wired to meet the requirements of a variety of applications and is well suited to extend an existing fire system.

It shares the same straightforward, intuitive interface as the BiWire Ultra and EFCV8Zone conventional panels, providing a proven solution for simple programming and maintenance.

The BiWire Flexi fire alarm system is certified to EN54 part2 and part 4 and is designed to meet the recommendations of BS5839.

Key Features

  • Configure zone wiring to work as either a conventional or two-wire system
  • Available in 2, 4 and 8 zone variants
  • Allows the connection of an existing conventional system to a BiWire system
  • Compatible with two-wire and conventional EN 54-23 certi ed visual alarm devices (VADs)

Benefits

  • Reduces stock-holding and enables the fire system to adapt to the demands of the customer or application
  • Simple to sell and specify, Flexi can be used in a wide variety of applications and is very simple to install
  • Save time, money and effort when undertaking system extensions and upgrades
  • Up-to-date with latest regulations
